Employees can now receive free underwear at select Japanese companies courtesy of Furipan, a company that prints advertisements on boxers.
In a brief questionnaire posted on Furipan's site, most men see their underwear approximately eight times a day, allowing for consistent exposure of the same product eight times. Any additional exposure to anyone but the wearer would most likely come from doing laundry. Since there isn't a lot of space in Japan and apartments are notoriously small, most home owners do not own a drier and clothes are often hung out to dry, which can allow neighbors to see the ads as well.
To sign up, employees can just go on the site and fill in their information to receive up to seven pairs of free ad-supported underwear shipped for free to their house each month.
